Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false and destructiveHint=false, so the basic safety profile is known. However, the description adds nothing beyond that: no mention of required permissions, what happens when a tenant with the same name already exists, whether creation is idempotent (annotations say it is not), or what the response returns.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
